Mike, of Ionian Enchantment, hosts the most recent Carnival of the Africans.   There are several posts worthy of your interest.  First up, Angela, the Skeptic Detective, tells us of a new twist in the vaccine-autism debate (and, yes, the people claiming that vaccines cause autism still do not have evidence to support their position). Second, Tim Beck at Reason Check has two interesting posts: Sangomas at University and Conspiracy Theorists and Creationists. Third, I thought it worthwhile to leap (or maybe just make a small jump) in defence of Koos Kombuis: George Claassen of Prometheus Unbound tells us that Kombuis believes in fairies. Maybe he does. But Kombuis also wrote The Complete Secret Diaries of God which was enormously entertaining and poked all kinds of fun at conventional religious practices. So, I forgive Koos for his dalliance with fairies. I was also fortunate enough to have three posts featured in the carnival: the use of randomized controlled trials in social science, the importance of evidence-based sex education, and how La Repubblica (an Italian newspaper) got happiness economics wrong.
